2D Correlation plots for each indicator distribution by merger sample. The bottom-left corner and top-right corner give the scatter plots of the indicator against the other. The diagonal shows the histogram of individual indicators. In the bottom-left panels, we overplot probability contours (varying probability value in each panel). In the top-right corner, we overplot ellipses indicating the shape of the Gaussian for all components with a weight concentration prior > 0.1. We note that ellipses match the location of the high probability contours.
